As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There will be two experimental groups, in which all subjects will receive joint mobilization treatment for their proximal tibiofibular joints and the talocrural joints. One of the experimental groups will receive additional proximal tibiofibular joint mobilization in the direction of anterior glide, while the other experimental group will receive additional proximal tibiofibular joint mobilization in the direction of posterior glide. Dosage of the mobilization will be 2 sets of 10 repetitions at each joint, twice a week for 3 weeks. The intervention will be given by a physical therapist.

Comparator / control treatment
The comparison group will also receive joint mobilization treatment, but only to the talocrural joint. Dosage of mobilization will be 2 sets of 10 repetitions at each joint, twice a week for 3 weeks. The intervention will be also given by a physical therapist.

Summary
Brief summary
The purpose of this study is to investigate the proportion of PTFJ hypomobility in subjects with ankle instability and to compare the effect of two kinds of mobilization approach. This study will be a randomized control trial and separate the subjects into two groups. Each group will receive treatments twice a week for 3 weeks. Evaluations of treatment effect include ankle dorsiflexion range of motion, tibial internal rotation range of motion, dynamic balance, landing performance, and self-feeling report.
